Shark spits out Spanish buttock in NSW

A Spanish tourist has an extraordinary traveller's tale of survival to tell after fighting off a shark while bodyboarding at a beach on the NSW South Coast.

Gonzalo Mompo Fernandez, aged in his late 20s, walked away with just a few scratches to his backside and leg after after a shark nipped him at Killalea State Park - also known as The Farm - near Shellharbour at dusk on Sunday.

He had been bodyboarding with about four mates and is understood to have been in Australia for two weeks.

Park manager Nathan Cattell, who rushed down to the scene shortly after 7pm, says a number of locals had witnessed "a grey shark, about 2-3 metres" come up behind the tourist in the water before latching on.

"To my disbelief, sure enough he had been bitten on the bum," Mr Cattell told AAP on Monday.
